Belt Pulley may Fail Causing Engine Overheat
Description
Cummins is recalling certain model ISB6.7 diesel engines manufactured from February 16, 2010, through May 4, 2012, equipped with fan pulley Part Number 3914462 and installed on certain Thomas Built Buses, Inc. school buses. The subject fan pulley is part of the accessory drive system on the front of the engine. This system is used to drive such components as the refrigerant compressors, the radiator fan, and the engine water pump. The web of the pulley can fatigue over time, causing the pulley to fail.
Injuries / Consequence
If this occurs, the fan belt may lose engagement of the water pump, allowing the cooling system to overheat. This may result in exceeding temperature limits, potentially disabling the school bus. If the school bus is occupied when it becomes disabled, the occupants would need to exit the vehicle and be transferred to another vehicle, putting them at risk of injury.
Remedy
Cummins will notify Thomas Built of this defect and the potential safety consequences, and will work with them to identify and notify the affected owners. Cummins will install a new fan drive pulley, without charge, through Cummins' service network. The recall began on November 27, 2012. Notification to owners began on January 4, 2013. Owners may contact Cummins at 1-812-377-5000.
